Presentation Transcript

Slide1: 

What is global warming? Why should we care? What can we do? Global Warning!

Slide2: 

We all use energy all day, everyday!

Slide3: 

Most of our energy comes from burning fossil fuels, such as coal, gas and oil.

Slide4: 

Fossil fuels are polluting our world and causing it to get hotter.

Slide5: 

Most scientists agree that pollution levels are contributing to global warming.

Slide6: 

There is little doubt that the temperature of the Earth is rising. The last decade was the warmest of the century, and the last century was the warmest of the millennium. Scientists predict that the Earth will warm by 1.4 - 5.8C in the next 95 years! The last Ice Age was only 5C colder than today. The Intergovernmental Panel on Climate Change (IPCC), a consortium of several thousand independent scientists.

Slide7: 

EffaithTy Gwydr / The Greenhouse Effect The gas from pollution traps the heat from the sun and causes our planet to overheat.

Slide8: 

Recent records show that our climate is getting warmer.

Slide9: 

Sea ice is melting.

Slide10: 

In America ice is disappearing. Our climate is already changing!

Slide11: 

Our sea levels are rising.

Slide12: 

Rising tides. Some scientists predict that a warmer climate will trigger more violent storms, which will cause increased rates of coastal erosion. Cape Hatteras in North Carolina in the USA. Our climate is already changing!

Slide13: 

Low-lying Bangladesh is prone to coastal flooding caused by storm surges, which have killed thousands of people in recent years. Experts say if the sea level goes up by 1 metre, Bangladesh will lose 17.5% of its land. Our climate is already changing!

Slide14: 

Experts predict that fierce storms and floods are likely to become more frequent in the future. If homes and factories continue to be built on floodplains, the cost of severe flooding will soar. UK October 2004 Our climate is already changing!

Slide15: 

The Intergovernmental Panel on Climate Change (IPCC), a consortium of several thousand independent scientists. Most scientists agree that pollution levels are contributing to global warming. Look at the graphs. What do you think?

Slide16: 

2029 How old will you or your children be? The way we live will determine the temperature. Worst case: if high pollution emissions In 25 years… Best case: if low pollution emissions

Slide17: 

2099 How old will your grandchildren be? The way we live will determine the temperature. Worst case: if high pollution emissions In 95 years… Best case: if low pollution emissions

Slide18: 

Newidiadau i gyfartaledd tymheredd blynyddol Predicted changes in annual average temperature

Slide19: 

Scientists predict that by 2080 Wales will experience: An average increase in temperature of by 2%

Slide20: 

More rain in winter and less rain in the summer Scientists predict that by 2080 Wales will experience:

Slide21: 

A rise in sea level that could range from 18-79 cm Scientists predict that by 2080 Wales will experience:

Slide22: 

More extreme weather conditions and very severe gales 10% more drought years Scientists predict that by 2080 Wales will experience:

Slide23: 

“Climate Change is a far greater threat to the world than international terrorism” Sir David King, UK Government's Chief Scientific Adviser If you don’t care, who will? “Global warming is the most serious threat facing the planet” Tony Blair Scientists predict that the Earth will warm by 1.4 - 5.8C in the next 95 years!

Slide24: 

Be energy – efficient! But what can I do? If every household installed two energy efficient light bulbs, enough energy would be saved in a year to supply all street lighting in the UK.

Slide25: 

Always remember to switch the bathroom light off after you go to the toilet.   Only fill the kettle with the amount of water you need.   Don't leave your computer on after you're finished using it.   If you feel cold try putting on a jumper before you turn up the heating.
